Instructions
Make the cake:
- Preheat the oven to 350°F. Line a 9 by 13-inch baking pan with parchment paper then spray with nonstick cooking spray.
- In a medium heatproof bowl add the chocolate, cocoa powder, and espresso powder. Pour hot water over mixture. Cover and let stand for 5 minutes. Whisk mixture gently until smooth then set aside to cool.
- In a small bowl, whisk together the flour, sugars, salt, and baking soda.
- Whisk the buttermilk, oil, eggs, egg yolk, and vanilla into the cooled chocolate mixture until smooth. Stir in the flour mixture until smooth, being careful not to overmix.
- Pour the batter into the prepared pan and bake for 35 minutes, or until a cake tester comes out clean. Don't overbake or your cake will be dry.
- Let cool completely.
Make the frosting:
- In a large glass bowl, microwave the chocolate and butter in 30 second bursts, stirring between bursts, until melted and smooth. Add the powdered sugar, cocoa powder, and half the milk and whisk until smooth. Gradually add remaining milk until the mixture is smooth and thickened to a batter like consistency. Pour all over cake. Allow to set before slicing and serving. Garnish with sprinkles, if desired.
Notes
- *Be sure to use a digital kitchen scale or the spoon and level method to measure the flour & cocoa powder.
